Changing isn't easy as the constants and structures are all named differently. They are all named "struct sockaddr_storage", no? You won't even need that most

Changing isn't easy as the constants and structures are all named differently. They are all named "struct sockaddr_storage", no? You won't even need that most of the time, as it's all dealt with by getaddrinfo and friends (see sibling comment). Sure, there are some cases where it breaks down but the vast majority of software doesn't go there.
